To all-'whom t may concern:

Be it known that we, McKrNNoN SUM- MERs and WILLIAM R.A VILEs,citizens of the United States, residing at Weldon, county of Dewitt, State of Illinois, and Clinton, ,county of Dewitt, and Statevof. Illinois, respectively, have invented certain new and useful Improvements in Refrigerating and Cooling Devices, of which the following is a specication.

Our invention relates to refrigerating devices y and adapted for omestic use.

The object of our invention is to provide a refrigerator especially adapted for domestic use provided with a chamber for containing the food stuffs and equipped with means for making its own ice. A further object of our invention is to provide, in a device of theclass mentioned, means where- 'by the device may -be utilized for cooling vide in la device of the class mentioned,y

means whereby the ice formed in the device may be rendered accessible..A Other o bjects will appear hereinafter.

With these objects in view. our invention consists generally in a casing provided with a food compartment and an adjacent compartment equipped with ice making apparawith means for orcing a current of air therethrough whereby' the heated air may be l removed from the upper portion of the room, cooled and again returned to the room in its cooledcondition. Our invention further consists'in providing a swinging 4base or platform arranged within the ice making compartment and arranging 'the ice makin apparatus and air cooling device upon t e same so that byswinging the platform outwardly the ice formed in the device may be rendered accessible. Our invention further consists" in a device as mentioned further characterized by providing the partition between the two chambers with an opening for giving access to the ice without necessitating swinging the apparatus outwardly from the casing. Our invention further consists in an improved closure ,for the compartment provided with the swinging articularly to refrigerators platform,

and particularly-pointed out in the claimsir Qur invention will be more readily understood by reference to the accompanying a portion of said closure being rigidlyattached to Kthe platform and a pordrawings, forming a part of this specifica- )tion and in whicherator embodying our invention, the same being taken upon and the upper 4portion ofthe device being illustrated in elevation,- and Fig. 2 is a horizontal section on the line y-y of Fig. 1. Referring now to the drawings, l indicates the body or casing of the refrigeratorl the line of Fig. 2`

Figure l is a vertical section of a refrigi which may be of any preferred size and practically any preferred form to suit the requirements of the conditions under which 4the same is to be used ;l that is, if for do- `mestic use, for which itis 'primarily designed, it may be of small size, but if for lunch rooms and the like, it may be of larger fsize and the arrangement in either case may be'made to suit the various conditions as will appear `as the description 'proceeds.

The casing is providedwith a partition 2 dividing the same into a food compartment '3 and a refrigerating compartment t. As shown in the drawings, the food compartment is arranged above the refrigerating compartment although it is obvious that this particular arrangement is not essential. 5 indicate doors for giving access to the compartment 3.

Arranged ithin the compartment 4 is an ice making apparatus and air cooling means.

The ice making mechanism comprises a brine tank 6 equipped with the receptacles '7 in which the ice is formed and provided -with ammonia tubes 8. A suitable ammonia pump is provided illustrated diagrammatically at 9 and this pump is actuated by 'any suitable motor power 4such as an electric motor 10. 11 indicates a switch arranged in the circuit to the motor by means of which the same may be started and stopped as desired. j The air cooling mechanism comprises a jacket 12 around the brine tank 6 forming an airfspacel preferably entirely around i io Larnaca thefour sides and bottom of said tank,` av The operation of the device is obvious conduit 14 leading into said jacketed space and an outlet 15 leading from said space and discharging into the atmosphre of the room in which' ie device is located; A fan 16 is interposed in the lconduit 14 for creating a circulation-of air and this is arranged to be driven yfrom the motor 10. lilie conduit 14 is extended beyond the fan 16 as at 14 to any height above the casing 1 asis desired.

lin order that the pump j9 and fan 16 @may be operated independently or simultaneously as desired, suitable clutches 17 and 18 are provided whereby the same may be respectively connected to or disconnected from the power shaft 19 of the motor. Any suitable clutch mechanism may be employed for this purpose, that shown in' Fig. 2 being merely diagrammatic. l

r1`he brine tank, thev pump, motor and fan are preferably arranged upon a platform 20 pivotally connected as at 21'to the casing 1' and swinging -upon ran arcuate track 22, the latter being provided to lessen the friction. 1t is'obvious that by swinging the platform 20 outwardly as shown in dotted lines in Fig. 2, the'ice which iskformed in the receptacle 7 is rendered accessible. However, in order that the ice may bem accessible without necessitating the swinging of the vplatform@ provide lthe partition 2, adjacent the receptacle 7, with an opening equipped with a closure 23. 1n the form shown in the drawings this closure would therefore constitute a portion of the bottom of the food containing chamber andthence it would not always be convenient to remove the closure 23. At such times the latform may be swung outwardly when itis desired to have access to the ice. rlihe swinging of the platform necessitates providing the extensionl v,14' of the air induction pipe with a fiexible portion 14a;- and theeduction pipe 15 is formed of two portions as shown clearly in fFig. 2, one portion being rigidly connected to the casing 1 and the other connected to' the jacket 12, the adj'acent ends being beveled as at 15' to facilitate swinging the platfornr and making a close joint. between the portions of the eduction pipe when .the platform is swung inwardly.

f 'A suitable closure is provided for the a portion 24 rigidly connected to the o ter edge of thechamber 4.' rllhis comprifs platform at its free end, and a hingedly mounted portion 25. When it is desired to swing the platform the portion 25 is swung backwardly against the portion 24as shown 1 in. dotted lines in Fig. 2 after which the platform is freeto swing. 1t is obvious that by this arrangement the portion 25 serves as a lock to 'prevent swinging of thebplatform 2O from the preceding description. "We claimz- `i j 1. 1n a refrigerator, ay casing provided with an opening in one of its walls, a platform pivotallyJnounted within saidcasing and adapted to swing outwardly through said opening, ice making apparatus on said platformnnd a closure comprising a vportion fixed to said platform andaportion hingedly connected to said fixed portion, substantially as described.

2. 1n a refrigerator, a casing provided with an opening in one of its walls, -a platform arranged ywithin said casing and pivotally connected thereto adjacent one end Jof said platform, said platform being arranged to swing outwardly through said opening, ice making apparatus on said platform and a closure for said opening comprising a fixed portion secured to the outerwedge of the platform adjacentv its free end and a portion hingedly connected tothe fixed portion and adapted to close the portion of said opening adjacent the ypivoted end of sth platform,l substantially as described. 3. 1n a refrigerator, a casing provided with an opening in-one of its walls, a swinging platform arranged within j said casing and adapted to swing outwardly throughj said opening, ice making apparatus on s aid platform and a closure. for vsaid opening comprising a fixed part secured to said plat-r form and aswinging portion serving as a -lock for said scribed. i

4. 1n a refrigerator, a casing provided with an opening in one of. its walls, a swin platforms substantially as deice' ing platform pivotally mounted within said v of two subscribing witnesses. l n' McKinnon' snes. wiLLiAi/i n. vines.
